Auburn officials issued an alert to fans to be wary of counterfeit tickets for Friday's Iron Bowl at Jordan-Hare Stadium.

The university said:

* Any ticket for sections 17-27 and the upper part of section 28 is counterfeit. That is the student section, and no tickets are printed for those sections.

* The photo on counterfeit tickets will often appear grainier and less crisp than an original ticket.

* Official tickets have several security features, including sliver security foil in the shape of the AU logo and a stadium diagram on the back of the ticket that reveals an AU logo when rubbed with a coin or key.

GAME DAY CHANGES: Auburn has modified its usual game day routine for Friday's game.

The university will close the core of campus -- the area bounded by Samford Avenue, Wire Road, Magnolia Avenue and College Street -- from 5 p.m on Tuesday through 6 a.m. on Thursday. No tailgate sites may be reserved until that time and any site markings will be removed.

Early-arrival time for recreational vehicles is at 10 a.m. on Wednesday.
